PC shuts down unexpectedly and becomes unresponsive - Attempted multiple fixes
In my opinion, this appears to be a hardware problem that may require an RMA for the CPU or motherboard. Others might have different solutions to try first. By now you've narrowed down several possibilities. You could reinsert the CPU and check for thermal paste or debris in the socket. Make sure the power connections are secure and there are no loose components causing shorts. It's possible the RAM or CPU needs a voltage adjustment. I've seen cases where slightly increasing voltage helped, but it can also damage the chip if not done carefully. Be very careful with this step—it might void your warranty. If you decide to try it, monitor closely and be prepared for the worst-case scenario. For everyone else, this is likely the final step: troubleshoot thoroughly before assuming a fix.
